    This is a bit random, but I was using my iPhone and I accidentally tapped the screen of my Apple Watch and it actually opened an app. I gently tested this again (no Apple products were harmed in this test) and I was able to essentially use the aluminum back of my iPhone and iPad as a stylus for my Apple Watch. However, the same doesn't work with aluminum to an iPhone or iPad screen.

    Can anyone explain how this works? I'm just curious :p

    Capacitance passing from your hand through the aluminum. The same way the :apple:Pencil, stylus and touch gloves work.
